Photorealistic Idol Portrait with Golden Rim Light

Photorealistic upper-body portrait of a beautiful fictional 20-year-old adult Japanese woman with an idol-like appearance. She has fair natural skin, a graceful neckline, and glossy dark brown hair gathered into a loose low bun with a few wispy strands framing her cheek. Her face is turned mostly away from the camera in a soft three-quarter back profile, revealing only part of her cheek and lips. She gently raises one hand near her mouth with long almond-shaped black and white glossy nails, creating a quiet, candid moment. She wears a soft black knit cardigan that has naturally slipped slightly off one shoulder over a delicate white floral camisole with subtle lace trim. The clothing remains secure and tasteful, with realistic knit texture, natural folds, fabric weight, and believable drape. The composition is a close upper-body crop from the top of the head to just below the chest, shot from slightly behind and above the shoulder. The elegant curve of the neck, shoulder, and collarbone becomes the visual focus. Warm late-afternoon sunlight streams through a nearby window as the key light, creating a golden rim light across her hair, shoulder, collarbone, and cheek. Cool ambient indoor light softly fills the shadows, preserving realistic color separation. Keep most of the skin naturally matte and textured, placing restrained highlights only on the illuminated collarbone, shoulder, neck, and cheek. Hair shows fine glossy reflections along individual strands. Minimal modern interior with a softly blurred gray wall and doorway in the background.
